Store scope associations on nodes via a ScopeCarrier trait (#1729)

Bugs fixed:

  • a labelled loop failed to compile with an internal error: every scoped
    pass entered the labelled statement as a scope, but no pass ever
    associated one
  • break and continue ignored their label at IL generation and always
    targeted the innermost loop; they now branch to the named loop, and an
    unmatched label is a compile error

Technical:

  • scope associations move from a SYMBOL_TABLE hash map onto the nodes
    themselves: scope-introducing node types implement a new ScopeCarrier
    trait, and associate/enter/leave take the trait type, so entering a
    scope on a non-carrying node is a compile error instead of a runtime
    lookup miss
  • the namespace scope association moves from the namespace's name
    identifier onto the NAMESPACE node
  • drops two dictionary lookups per scope node per pass and the per-build
    scope map allocation
